FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wirelesscommunication and to techniques and apparatuses for paging indication.

BACKGROUND

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, and/or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations(BSs) that can support communication for a number of user equipment(UEs). A user equipment (UE) may communicate with a base station (BS)via the downlink and uplink. The downlink (or forward link) refers tothe communication link from the BS to the UE, and the uplink (or reverselink) refers to the communication link from the UE to the BS. As will bedescribed in more detail herein, a BS may be referred to as a Node B, agNB, an access point (AP), a radio head, a transmit receive point (TRP),a New Radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. New Radio (NR), which may also bereferred to as 5G, is a set of enhancements to the LTE mobile standardpromulgated by the Third Generation Partnership Project (3GPP). NR isdesigned to better support mobile broadband Internet access by improvingspectral efficiency, lowering costs, improving services, making use ofnew spectrum, and better integrating with other open standards usingorthogonal frequency division multiplexing (OFDM) with a cyclic prefix(CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g.,also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) onthe uplink (UL), as well as supporting beamforming, multiple-inputmultiple-output (MIMO) antenna technology, and carrier aggregation.However, as the demand for mobile broadband access continues toincrease, there exists a need for further improvements in LTE and NRtechnologies. Preferably, these improvements should be applicable toother multiple access technologies and the telecommunication standardsthat employ these technologies.

Various aspects of the disclosure are described more fully hereinafterwith reference to the accompanying drawings. This disclosure may,however, be embodied in many different forms and should not be construedas limited to any specific structure or function presented throughoutthis disclosure. Rather, these aspects are provided so that thisdisclosure will be thorough and complete, and will fully convey thescope of the disclosure to those skilled in the art. Based on theteachings herein one skilled in the art should appreciate that the scopeof the disclosure is intended to cover any aspect of the disclosuredisclosed herein, whether implemented independently of or combined withany other aspect of the disclosure. For example, an apparatus may beimplemented or a method may be practiced using any number of the aspectsset forth herein.

Itshould be understood that any aspect of the disclosure disclosed hereinmay be embodied by one or more elements of a claim.

Several aspects of telecommunication systems will now be presented withreference to various apparatuses and techniques. These apparatuses andtechniques will be described in the following detailed description andillustrated in the accompanying drawings by various blocks, modules,components, circuits, steps, processes, algorithms, and/or the like(collectively referred to as “elements”). These elements may beimplemented using hardware, software, or combinations thereof. Whethersuch elements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

It should be noted that while aspects may be described herein usingterminology commonly associated with 3G and/or 4G wireless technologies,aspects of the present disclosure can be applied in othergeneration-based communication systems, such as 5G and later, includingNR technologies.

FIG. 1 is a diagram illustrating a wireless network 100 in which aspectsof the present disclosure may be practiced. The wireless network 100 maybe an LTE network or some other wireless network, such as a 5G or NRnetwork. The wireless network 100 may include a number of BSs 110 (shownas BS 110 a, BS 110 b, BS 110 c, and BS 110 d) and other networkentities. ABS is an entity that communicates with user equipments (UEs)and may also be referred to as a base station, a NR BS, a Node B, a gNB,a 5G node B (NB), an access point, a transmit receive point (TRP),and/or the like. Each BS may provide communication coverage for aparticular geographic area. In 3GPP, the term “cell” can refer to acoverage area of a BS and/or a BS subsystem serving this coverage area,depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). ABS for a macro cell may bereferred to as a macro BS. ABS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1, a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some aspects, the BSs may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in thewireless network 100 through various types of backhaul interfaces suchas a direct physical connection, a virtual network, and/or the likeusing any suitable transport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1, a relay station 110 d may communicate with macro BS 110 a and aUE 120 d in order to facilitate communication between BS 110 a and UE120 d. A relay station may also be referred to as a relay BS, a relaybase station, a relay, and/or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, e.g., directly or indirectly via a wireless orwireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, and/or the like. A UE may be a cellularphone (e.g., a smart phone), a personal digital assistant (PDA), awireless modem, a wireless communication device, a handheld device, alaptop computer, a cordless phone, a wireless local loop (WLL) station,a tablet, a camera, a gaming device, a netbook, a smartbook, anultrabook, a medical device or equipment, biometric sensors/devices,wearable devices (smart watches, smart clothing, smart glasses, smartwrist bands, smart jewelry (e.g., smart ring, smart bracelet)), anentertainment device (e.g., a music or video device, or a satelliteradio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, location tags, and/or the like, that may communicate with abase station, another device (e.g., remote device), or some otherentity. A wireless node may provide, for example, connectivity for or toa network (e.g., a wide area network such as Internet or a cellularnetwork) via a wired or wireless communication link. Some UEs may beconsidered Internet-of-Things (IoT) devices, and/or may be implementedas NB-IoT (narrowband internet of things) devices. Some UEs may beconsidered a Customer Premises Equipment (CPE). UE 120 may be includedinside a housing that houses components of UE 120, such as processorcomponents, memory components, and/or the like.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular radioaccess technology (RAT) and may operate on one or more frequencies. ARAT may also be referred to as a radio technology, an air interface,and/or the like. A frequency may also be referred to as a carrier, afrequency channel, and/or the like. Each frequency may support a singleRAT in a given geographic area in order to avoid interference betweenwireless networks of different RATs. In some cases, NR or 5G RATnetworks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120e) may communicate directly using one or more sidelink channels (e.g.,without using a base station 110 as an intermediary to communicate withone another). For example, the UEs 120 may communicate usingpeer-to-peer (P2P) communications, device-to-device (D2D)communications, a vehicle-to-everything (V2X) protocol (e.g., which mayinclude a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure(V2I) protocol, and/or the like), a mesh network, and/or the like. Inthis case, the UE 120 may perform scheduling operations, resourceselection operations, and/or other operations described elsewhere hereinas being performed by the base station 110.

As indicated above, FIG. 1 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 1.

FIG. 2 shows a block diagram of a design 200 of base station 110 and UE120, which may be one of the base stations and one of the UEs in FIG. 1.Base station 110 may be equipped with T antennas 234 a through 234 t,and UE 120 may be equipped with R antennas 252a through 252r, where ingeneral T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from adata source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (e.g., encodeand modulate) the data for each UE based at least in part on the MCS(s)selected for the UE, and provide data symbols for all UEs. Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI) and/or the like) and controlinformation (e.g., CQI requests, grants, upper layer signaling, and/orthe like) and provide overhead symbols and control symbols. Transmitprocessor 220 may also generate reference symbols for reference signals(e.g., the cell-specific reference signal (CRS)) and synchronizationsignals (e.g., the primary synchronization signal (PSS) and secondarysynchronization signal (SSS)). A transmit (TX) multiple-inputmultiple-output (MIMO) processor 230 may perform spatial processing(e.g., precoding) on the data symbols, the control symbols, the overheadsymbols, and/or the reference symbols, if applicable, and may provide Toutput symbol streams to T modulators (MODs) 232 a through 232 t. Eachmodulator 232 may process a respective output symbol stream (e.g., forOFDM and/or the like) to obtain an output sample stream. Each modulator232 may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal. Tdownlink signals from modulators 232 a through 232 t may be transmittedvia T antennas 234 a through 234 t, respectively. According to variousaspects described in more detail below, the synchronization signals canbe generated with location encoding to convey additional information.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110 and/or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (e.g., filter, amplify,downconvert, and digitize) a received signal to obtain input samples.Each demodulator 254 may further process the input samples (e.g., forOFDM and/or the like) to obtain received symbols. A MIMO detector 256may obtain received symbols from all R demodulators 254 a through 254 r,perform MIMO detection on the received symbols if applicable, andprovide detected symbols. A receive processor 258 may process (e.g.,demodulate and decode) the detected symbols, provide decoded data for UE120 to a data sink 260, and provide decoded control information andsystem information to a controller/processor 280. A channel processormay determine reference signal received power (RSRP), received signalstrength indicator (RSSI), reference signal received quality (RSRQ),channel quality indicator (CQI), and/or the like. In some aspects, oneor more components of UE 120 may be included in a housing.

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to basestation 110. At base station 110, the uplink signals from UE 120 andother UEs may be received by antennas 234, processed by demodulators232, detected by a MIMO detector 236 if applicable, and furtherprocessed by a receive processor 238 to obtain decoded data and controlinformation sent by UE 120. Receive processor 238 may provide thedecoded data to a data sink 239 and the decoded control information tocontroller/processor 240. Base station 110 may include communicationunit 244 and communicate to network controller 130 via communicationunit 244. Network controller 130 may include communication unit 294,controller/processor 290, and memory 292.

Controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform one ormore techniques associated with paging indication, as described in moredetail elsewhere herein. For example, controller/processor 240 of basestation 110, controller/processor 280 of UE 120, and/or any othercomponent(s) of FIG. 2 may perform or direct operations of, for example,process 800 of FIG. 8 and/or other processes as described herein.Memories 242 and 282 may store data and program codes for base station110 and UE 120, respectively. In some aspects, memory 242 and/or memory282 may comprise a non-transitory computer-readable medium storing oneor more instructions for wireless communication. For example, the one ormore instructions, when executed by one or more processors of the basestation 110 and/or the UE 120, may perform or direct operations of, forexample, process 800 of FIG. 8 and/or other processes as describedherein. A scheduler 246 may schedule UEs for data transmission on thedownlink and/or uplink.

In some aspects, UE 120 may include means for receiving a referencesignal or channel conveying a paging indicator; means for determining,based on the paging indicator, whether to monitor a paging controlchannel including a scheduling grant for a paging shared channelcommunication; means for estimating time or frequency information forreceiving the paging control channel based at least in part on a resultof the determining; means for receiving the paging control channelcontaining based at least in part on the result of the determining andthe estimated time or frequency information; means for skippingmonitoring the paging control channel based at least in part on theresult of the determining; and/or the like. In some aspects, such meansmay include one or more components of UE 120 described in connectionwith FIG. 2, such as controller/processor 280, transmit processor 264,TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector256, receive processor 258, and/or the like.

As indicated above, FIG. 2 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 2.

FIG. 3A shows an example frame structure 300 for frequency divisionduplexing (FDD) in a telecommunications system (e.g., NR). Thetransmission timeline for each of the downlink and uplink may bepartitioned into units of radio frames (sometimes referred to asframes). Each radio frame may have a predetermined duration (e.g., 10milliseconds (ms)) and may be partitioned into a set of Z (Z≥1)subframes (e.g., with indices of 0 through Z−1). Each subframe may havea predetermined duration (e.g., 1 ms) and may include a set of slots(e.g., 2^(m) slots per subframe are shown in FIG. 3A, where m is anumerology used for a transmission, such as 0, 1, 2, 3, 4, and/or thelike). Each slot may include a set of L symbol periods. For example,each slot may include fourteen symbol periods (e.g., as shown in FIG.3A), seven symbol periods, or another number of symbol periods. In acase where the subframe includes two slots (e.g., when m=1), thesubframe may include 2L symbol periods, where the 2L symbol periods ineach subframe may be assigned indices of 0 through 2L−1. In someaspects, a scheduling unit for the FDD may be frame-based,subframe-based, slot-based, symbol-based, and/or the like.

While some techniques are described herein in connection with frames,subframes, slots, and/or the like, these techniques may equally apply toother types of wireless communication structures, which may be referredto using terms other than “frame,” “subframe,” “slot,” and/or the likein 5G NR. In some aspects, “wireless communication structure” may referto a periodic time-bounded communication unit defined by a wirelesscommunication standard and/or protocol. Additionally, or alternatively,different configurations of wireless communication structures than thoseshown in FIG. 3A may be used.

In certain telecommunications (e.g., NR), a base station may transmitsynchronization signals. For example, a base station may transmit aprimary synchronization signal (PSS), a secondary synchronization signal(SSS), and/or the like, on the downlink for each cell supported by thebase station. The PSS and SSS may be used by UEs for cell search andacquisition. For example, the PSS may be used by UEs to determine symboltiming, and the SSS may be used by UEs to determine a physical cellidentifier, associated with the base station, and frame timing. The basestation may also transmit a physical broadcast channel (PBCH). The PBCHmay carry some system information, such as system information thatsupports initial access by UEs.

In some aspects, the base station may transmit the PSS, the SSS, and/orthe PBCH in accordance with a synchronization communication hierarchy(e.g., a synchronization signal (SS) hierarchy) including multiplesynchronization communications (e.g., SS blocks), as described below inconnection with FIG. 3B.

FIG. 3B is a block diagram conceptually illustrating an example SShierarchy, which is an example of a synchronization communicationhierarchy. As shown in FIG. 3B, the SS hierarchy may include an SS burstset, which may include a plurality of SS bursts (identified as SS burst0 through SS burst B−1, where B is a maximum number of repetitions ofthe SS burst that may be transmitted by the base station). As furthershown, each SS burst may include one or more SS blocks (identified as SSblock 0 through SS block (b_(max_SS)-1), where b_(max_SS-)1 is a maximumnumber of SS blocks that can be carried by an SS burst). In someaspects, different SS blocks may be beam-formed differently. An SS burstset may be periodically transmitted by a wireless node, such as every Xmilliseconds, as shown in FIG. 3B. In some aspects, an SS burst set mayhave a fixed or dynamic length, shown as Y milliseconds in FIG. 3B.

The SS burst set shown in FIG. 3B is an example of a synchronizationcommunication set, and other synchronization communication sets may beused in connection with the techniques described herein. Furthermore,the SS block shown in FIG. 3B is an example of a synchronizationcommunication, and other synchronization communications may be used inconnection with the techniques described herein.

In some aspects, an SS block includes resources that carry the PSS, theSSS, the PBCH, and/or other synchronization signals (e.g., a tertiarysynchronization signal (TSS)) and/or synchronization channels. In someaspects, multiple SS blocks are included in an SS burst, and the PSS,the SSS, and/or the PBCH may be the same across each SS block of the SSburst. In some aspects, a single SS block may be included in an SSburst. In some aspects, the SS block may be at least four symbol periodsin length, where each symbol carries one or more of the PSS (e.g.,occupying one symbol), the SSS (e.g., occupying one symbol), and/or thePBCH (e.g., occupying two symbols).

In some aspects, the symbols of an SS block are consecutive, as shown inFIG. 3B. In some aspects, the symbols of an SS block arenon-consecutive. Similarly, in some aspects, one or more SS blocks ofthe SS burst may be transmitted in consecutive radio resources (e.g.,consecutive symbol periods) during one or more slots. Additionally, oralternatively, one or more SS blocks of the SS burst may be transmittedin non-consecutive radio resources.

In some aspects, the SS bursts may have a burst period, whereby the SSblocks of the SS burst are transmitted by the base station according tothe burst period. In other words, the SS blocks may be repeated duringeach SS burst. In some aspects, the SS burst set may have a burst setperiodicity, whereby the SS bursts of the SS burst set are transmittedby the base station according to the fixed burst set periodicity. Inother words, the SS bursts may be repeated during each SS burst set.

The base station may transmit system information, such as systeminformation blocks (SIBs) on a physical downlink shared channel (PDSCH)in certain slots. The base station may transmit control information/dataon a physical downlink control channel (PDCCH) in C symbol periods of aslot, where B may be configurable for each slot. The base station maytransmit traffic data and/or other data on the PDSCH in the remainingsymbol periods of each slot.

As indicated above, FIGS. 3A and 3B are provided as examples. Otherexamples may differ from what is described with regard to FIGS. 3A and3B.

FIG. 4 shows an example slot format 410 with a normal cyclic prefix. Theavailable time frequency resources may be partitioned into resourceblocks. Each resource block may cover a set of subcarriers (e.g., 12subcarriers) in one slot and may include a number of resource elements.Each resource element may cover one subcarrier in one symbol period(e.g., in time) and may be used to send one modulation symbol, which maybe a real or complex value.

An interlace structure may be used for each of the downlink and uplinkfor FDD in certain telecommunications systems (e.g., NR). For example, Qinterlaces with indices of 0 through Q−1 may be defined, where Q may beequal to 4, 6, 8, 10, or some other value. Each interlace may includeslots that are spaced apart by Q frames. In particular, interlace q mayinclude slots q, q+Q, q+2Q, etc., where q ∈ {0, . . . , Q−1}.

A UE may be located within the coverage of multiple BSs. One of theseBSs may be selected to serve the UE. The serving BS may be selectedbased at least in part on various criteria such as received signalstrength, received signal quality, path loss, and/or the like. Receivedsignal quality may be quantified by a signal-to-noise-and-interferenceratio (SNIR), or a reference signal received quality (RSRQ), or someother metric.

FIG. 5 illustrates an example logical architecture of a distributed RAN500, according to aspects of the present disclosure. A 5G access node506 may include an access node controller (ANC) 502. The ANC may be acentral unit (CU) of the distributed RAN 500. The backhaul interface tothe next generation core network (NG-CN) 504 may terminate at the ANC.The backhaul interface to neighboring next generation access nodes(NG-ANs) may terminate at the ANC. The ANC may include one or more TRPs508 (which may also be referred to as BSs, NR BSs, Node Bs, 5G NBs, APs,gNB, or some other term). As described above, “TRP” may be usedinterchangeably with “cell.”

The TRPs 508 may be a distributed unit (DU). The TRPs may be connectedto one ANC (ANC 502) or more than one ANC (not illustrated). Forexample, for RAN sharing, radio as a service (RaaS), and servicespecific AND deployments, the TRP may be connected to more than one ANC.A TRP may include one or more antenna ports. The TRPs may be configuredto individually (e.g., dynamic selection) or jointly (e.g., jointtransmission) serve traffic to a UE.

For example, thearchitecture may be based at least in part on transmit networkcapabilities (e.g., bandwidth, latency, and/or jitter).

The architecture may share features and/or components with LTE.According to aspects, the next generation AN (NG-AN) 510 may supportdual connectivity with NR. The NG-AN may share a common fronthaul forLTE and NR.

As indicated above, FIG. 6 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 6.

In some communications systems, such as 5G, a UE may utilize a low powerstate to reduce power consumption during periods of time when, forexample, the UE is not scheduled to receive data from a BS on a downlinkor transmit data to the BS on the uplink. For example, in discontinuousreception (DRX) operation, the UE may periodically enter a low-powerstate, which may be termed a sleep state, in which the UE uses lesspower than in a normal-power state, which may be termed an awake state.Periodically, the UE may transition from the low-power state to thenormal-power state to receive signaling from the BS and/or to transmitsignaling to the BS.

However, transitioning from the low-power state to the normal-powerstate may result in increased utilization of power resources relative toremaining in the low-power state. In some cases, the UE may transitionto the normal power state, but signaling may not be scheduled for theUE. Thus, some aspects described herein provide for a reference signalor channel that conveys paging indication. For example, during a firstperiod of time, the UE may monitor for a reference signal or channelfrom the BS indicating whether to monitor for a downlink channel (e.g.,a physical downlink control channel (PDCCH) and/or a physical downlinkshared channel (PDSCH)). In this case, the paging indicator may indicatewhether a page is scheduled for transmission to the UE. When a page isscheduled for transmission, the UE may remain in the normal-power stateto monitor for the page. In contrast, when a page is not scheduled fortransmission, the UE may skip switching to the normal-power state for,for example, a plurality of paging cycles, thereby reducing autilization of power resources.

FIGS. 7A and 7B are diagrams illustrating examples 700/700′ of pagingindication, in accordance with various aspects of the presentdisclosure. As shown in FIGS. 7A and 7B, examples 700/700′ include a BS110 and a UE 120.

As further shown in FIG. 7A, and by reference number 710, BS 110 maytransmit and UE 120 may receive a reference signal or channel includinga paging indicator. For example, during a first period of a DRX cycle,UE 120 may receive a paging indicator indicating whether UE 120 is toskip switching to the normal-power state for one or more subsequentpaging cycles. In some aspects, UE 120 may receive informationidentifying a configuration indicating the time and/or frequencyresource for monitoring and receiving the reference signal or channel.For example, UE 120 may determine a paging frame and a paging occasionbased at least in part on a paging cycle and a UE identifier of UE 120.In this case, UE 120 may determine the resources for monitoringreference signal or channel based at least in part on the paging frame,the paging occasion, and a time offset value (e.g., a fixed offset valueor a system information-configured offset value). In some aspects, UE120 may perform time and/or frequency tracking or estimation using thereference signal or channel. In this case, based at least in part onperforming time and/or frequency tracking or estimation, UE 120 mayreceive a subsequent communication.

In some aspects, BS 110 may quasi-co-locate (QCL) the reference signalor channel with a synchronization signal block (SSB). Furthermore, BS110 may quasi-co-locate (QCL) the reference signal or channel with adownlink channel. For example, BS 110 may transmit a paging PDCCH/PDSCHquasi-co-located with the reference signal or channel. In this case,there may be multiple resources for the reference signal or channel, andone or more resources may be associated with a single SSB and eachresource may correspond to a beam for transmission of the referencesignal. Further, UE 120 may acquire a reception beam for successfullyreceiving the reference signal and use the beam to receive a broadcastchannel. Additionally, or alternatively, BS 110 may transmit thereference signal using a narrower beam than the SSB. For example, afirst beam of the reference signal may be located within a second, widerbeam of the SSB. In this case, BS 110 may transmit a downlink channelover the narrower beam for coverage enhancement.

In some aspects, UE 120 may use information regarding the SSB to receivethe reference signal or channel based at least in part on BS 110quasi-co-locating the reference signal with the SSB transmission. Forexample, UE 120 may obtain the SSB for determining and/or refiningtiming synchronization and/or frequency synchronization and use the SSBto derive a receive beam for reception of the reference signal.Additionally, or alternatively, UE 120 may determine a time resource,frequency resource, receive beam and/or the like for receiving thereference signal and the broadcast channel based on the referencesignal.

In some aspects, UE 120 may determine a characteristic of a radioresource management measurement based at least in part on the referencesignal. For example, UE 120 may determine to relax a radio resourcemanagement measurement based at least in part on a cell quality bymeasuring the RSRP of the reference signal. In this case, based at leastin part on the cell quality satisfying a threshold, UE 120 may forgoperforming one or more neighbor cell measurements, thereby reducingpower utilization, utilization of network resources, and/or the like. Inthis way, UE 120 avoids a delay in switching from the normal-power stateto the low-power state relative to deriving the cell quality from asynchronization signal or physical broadcast channel measurement.

As further shown by reference number 720, UE 120 may receive thereference signal including a paging indicator and determine to monitorfor and receive paging in the next paging cycle rather than skippingmonitoring. In this case, UE 120 may track or estimate time and/orfrequency resources using the reference signal, and may receive acommunication based at least in part on tracking or estimating the timeand/or frequency resources. In contrast, as shown in FIG. 7B, and byreference number 720′, UE 120 may receive a reference signal indicatingthat UE 120 is to skip monitoring in one or more subsequent DRX cyclesand may forgo switching to the normal-power state for a second period.In this case, UE 120 may forgo switching from the low-power mode to anormal-power mode during a second period of the DRX cycle that isreserved for paging. Additionally, or alternatively, UE 120 may forgomonitoring for a PDCCH and/or PDSCH during the DRX cycle based at leastin part on the reference signal. In this way, UE 120 reduces a powerutilization relative to switching to the normal-power state when UE 120is not scheduled to receive, for example, a PDCCH or a PDSCH. In someaspects, the reference signal or channel may include a paging indicationidentifying a particular quantity of DRX cycles for which to skipmonitoring. For example, UE 120 may determine, based at least in part onthe reference signal, whether to skip monitoring for a plurality ofconsecutive DRX cycles, a plurality of non-consecutive DRX cyclesaccording to an identified pattern, and/or the like.

In some aspects, UE 120 may receive the reference signal via a periodictransmission. For example, BS 110 may use, to convey the pagingindication associated with the reference signal, a periodic referencesignal associated with radio resource management and/or beam refinementfor downlink channels. In this case, the reference signal or channel mayinclude information identifying a skip of one or more DRX cycles.Additionally, or alternatively, UE 120 may receive the reference signalor channel via a non-periodic transmission. For example, when a page isscheduled for a paging occasion, BS 110 may transmit the referencesignal in connection with the page. In contrast, when a page is notscheduled for the paging occasion, BS 110 may forgo transmission of thereference signal. In this case, the reference signal may only indicate askip of a single DRX cycle.

In some aspects, the reference signal may include information indicatingthat paging is present for, for example, a group of UEs. In this case,the group of UEs may attempt to receive the paging and another group ofUEs, not indicated by the reference signal, may forgo attempting toreceive the paging. In some aspects, the reference signal may include asequence or identifier to indicate which UE or UEs are to attempt toreceive the paging.

As indicated above, FIGS. 7A and 7B are provided as examples. Otherexamples may differ from what is described with respect to FIGS. 7A and7B.
